Comments for VirtualBox : Extend Virtual Disk and File System

Craig said...

Excellent step by step example extending a disk and logical volume!

Tim Aiken said...

This did not work for me. I received:
[root@crs ~]# lvextend --size +11.99G --resizefs /dev/vg_oraclelinux6/lv_root
Logical volume lv_root successfully resized
fsadm: Filesystem "btrfs" on device "/dev/mapper/vg_oraclelinux6-lv_root" is not supported by this tool
fsadm failed:1

Thanks for the great and accurate step-by-step guidance, it helped me a lot! Only one thing that I used differently was extending the logical volume to the maximum of free extents by using the following option in the lvextend command:
lvextend -l +100%FREE --resizefs /dev/vg_ol6112/lv_root

Thank you!

I had the same message: fsadm: Filesystem "btrfs" on device "/dev/mapper/vg_oraclelinux6-lv_root" is not supported by this tool fsadm failed: 1

It took me a while to find out that LVM is using btrfs as their file system in my case. This command solved my problem:

[root@oraclelinux6 ~]# btrfs filesystem resize max /

Thanks for the heads-up. I've added your comment to the article. :)

I went through many google results and this is the only one clear enough and working for me (most other instructions make use of a GUI tool to manipulate the partition, which is not an option for me).

These instructions are very clear and make sense. Thanks again!
